Vehicle suspension device

Abstract

A vehicle suspension device according to the present invention is a suspension device and includes: a leaf spring; a locking member to which one end of the leaf spring is locked; and a holding member configured to hold another end of the leaf spring. The holding member includes: a roller configured to hold the other end of the leaf spring and be rotatable while following displacement of the other end of the leaf spring; and a pressing member facing the roller, and the other end of the leaf spring is provided between the roller and the pressing member.

1 . A vehicle suspension device comprising:
 a leaf spring;   a locking member to which one end of the leaf spring is locked; and   a holding member configured to hold another end of the leaf spring, wherein   the holding member includes:
 a roller configured to hold the other end of the leaf spring and be rotatable while following displacement of the other end of the leaf spring; and 
 a pressing member facing the roller, and 
   the other end of the leaf spring is provided between the roller and the pressing member.   
     
     
         2 . The vehicle suspension device according to  claim 1 , wherein the other end of the leaf spring is sandwiched between and held by the roller and the pressing member. 
     
     
         3 . The vehicle suspension device according to  claim 1 , further comprising:
 a biasing member configured to bias the roller and the pressing member in a direction in which the roller and the pressing member approach each other.   
     
     
         4 . The vehicle suspension device according to  claim 1 , wherein the pressing member is a roller that is rotatable while following displacement of the other end of the leaf spring. 
     
     
         5 . The vehicle suspension device according to  claim 1 , wherein at least one recess is formed on an outer circumferential surface of the roller. 
     
     
         6 . The vehicle suspension device according to  claim 4 , wherein at least one recess is formed on an outer circumferential surface of at least one of the roller and the pressing member. 
     
     
         7 . The vehicle suspension device according to  claim 1 , wherein the roller includes:
 a shaft part; and   a rotation part provided on an outer circumference of the shaft part, and configured to be rotatable with respect to the shaft part, the rotation part including an elastic material.   
     
     
         8 . The vehicle suspension device according to  claim 1 , wherein a protrusion protruding in a direction intersecting an axial direction is formed on at least one end side in the axial direction of the roller.
